Product Description
The composite suspension insulator is a high-performance product designed for high-voltage overhead power transmission and distribution infrastructure, serving as a critical component in both new line construction and maintenance projects.
The Composite Suspension Insulator Featuring an innovative design, this composite insulator is lighter and more breakage-resistant than traditional insulators; this reduces transportation costs and simplifies packaging and storage while overcoming the limitations of conventional insulation. It comprises three core elements - a reinforced fiberglass core rod, a High-Temperature Vulcanized (HTV) silicone rubber housing, and metal end fittings - forming a lightweight, streamlined assembly capable of meeting diverse application needs.
The HTV silicone rubber housing offers excellent hydrophobicity, effectively resisting the adverse effects of dust, chemical pollutants, salt spray, moisture accumulation, and high ambient humidity.


With superior wear resistance, it eliminates the corrosion issues common in traditional fiberglass insulators and significantly enhances grid safety and stability. The use of high-strength steel ensures product stability and durability under continuous loads.
The Composite Suspension Insulator maintains excellent insulating properties across various environments, including coastal regions, industrial zones, mining areas (including those with coal dust), and high-altitude locations.
Each unit undergoes rigorous factory testing and is backed by test reports from independent third-party laboratories, ensuring compliance with international IEC standards and suitability for global engineering projects.
To meet specific project requirements, we offer flexible configuration options and various connection methods, providing advanced, customized insulation solutions for high-voltage power transmission projects worldwide.

Our Advantage
With over 20 years of experience in the power transmission and distribution sector, we specialize in the R&D and manufacturing of composite post and suspension insulators. We possess deep insight into the operational requirements of various marine energy projects and provide expert technical support.
Every product undergoes rigorous electrical and mechanical performance testing before leaving the factory. Manufactured in strict accordance with international IEC standards, our products offer stable, reliable performance, effectively minimizing the risk of operational failures in the field.
We utilize HTV (High-Temperature Vulcanized) silicone rubber housings that offer enduring hydrophobicity and hydrophobicity transfer properties. Our products resist arcing under polluted conditions, UV aging, and corrosion, ensuring stable operation in harsh environments such as coastal areas with salt spray, industrial zones with chemical dust, and high-altitude regions.
We offer composite insulators covering voltage ratings from 10kV to 220kV. We provide customization options - including dry arc distance, structural dimensions, end-fitting types, and custom marking - to meet tender specifications and specific site requirements.
Operating our own manufacturing facilities, we possess robust production capabilities and full control over delivery schedules. We handle everything from small-batch sample orders to large-scale projects with flexibility, offering adaptable Minimum Order Quantities (MOQs) and eliminating intermediary markups.
